Java Program To Implement Method Overloading

Chapter: Miscellaneous Last Updated: 16-04-2023 12:42:00 UTC

Program:

            /* ............... START ............... */
                
public class MethodOverloadingExample {
    public static void main(String[] args) {
        MethodOverloadingExample obj = new MethodOverloadingExample();
        obj.print();
        obj.print(10);
        obj.print("Hello, World!");
    }

    // Method with no parameters
    void print() {
        System.out.println("This is an example of method overloading");
    }

    // Method with an integer parameter
    void print(int num) {
        System.out.println("Number: " + num);
    }

    // Method with a string parameter
    void print(String str) {
        System.out.println("String: " + str);
    }
}

                /* ............... END ............... */
        

Output

This is an example of method overloading

Number: 10

String: Hello, World!

> The first print() method is called with no arguments, so it simply prints the message "This is an example 
  of method overloading" to the console.

> The second print() method is called with an integer argument of 10, so it prints the message "Number: 10" 
  to the console.

> The third print() method is called with a string argument of "Hello, World!", so it prints the message 
  "String: Hello, World!" to the console.

> Note that each of these three print() methods has the same name, but Java is able to distinguish between 
  them based on their parameters. This is the essence of method overloading - having multiple methods with 
  the same name, but different parameters, so that we can use the same name for related functionality.

Notes:

• This program demonstrates the concept of method overloading in Java. Method overloading is a way to define multiple methods in a class with the same name, but with different parameters. In this program, we define three methods called print() with different parameter lists.
• The first print() method takes no parameters and simply prints a message to the console. The second print() method takes an integer parameter and prints the value of that parameter to the console. The third print() method takes a string parameter and prints the value of that parameter to the console.
• In the main() method of the program, we create an instance of the MethodOverloadingExample class and call each of the three print() methods with different arguments. Because each print() method has a different set of parameters, Java is able to distinguish between them and call the appropriate method based on the arguments we pass in.
• This program demonstrates the flexibility and convenience that method overloading provides in Java. By defining multiple methods with the same name but different parameters, we can use the same method name for related functionality, which can make our code more concise and easier to read.
